Allying topology and shape optimization through machine learning algorithms

چکیده
Structural optimization is part of the mechanical engineering field and, in most cases, tries to minimize overall weight a given design domain, subjected functionality constraints terms stresses or displacements. The relevant techniques are topology and shape optimization. Topology provides optimal material distribution layout into given, static, domain. On other hand, combination parameters that define required parametrization domain's boundary. Both have strengths weaknesses, thus hybrid approach combines former will more general structural framework take advantage their synergistic combination. difficulty arises when communicating both for which, this paper, we propose machine learning-based methodology.

Comparative Analysis of Machine Learning Algorithms with Optimization Purposes
The field of optimization and machine learning are increasingly interplayed and optimization in different problems leads to the use of machine learning approaches. Machine learning algorithms work in reasonable computational time for specific classes of problems and have important role in extracting knowledge from large amount of data. In this paper, a methodology has been employed to opt...
متن کاملSpatiotemporal Estimation of PM2.5 Concentration Using Remotely Sensed Data, Machine Learning, and Optimization Algorithms
PM 2.5 (particles <2.5 μm in aerodynamic diameter) can be measured by ground station data in urban areas, but the number of these stations and their geographical coverage is limited. Therefore, these data are not adequate for calculating concentrations of Pm2.5 over a large urban area. This study aims to use Aerosol Optical Depth (AOD) satellite images and meteorological data from 2014 to 2017 ...
متن کاملMachine learning algorithms in air quality modeling
Modern studies in the field of environment science and engineering show that deterministic models struggle to capture the relationship between the concentration of atmospheric pollutants and their emission sources. The recent advances in statistical modeling based on machine learning approaches have emerged as solution to tackle these issues. It is a fact that, input variable type largely affec...
متن کاملAdaptive Topology and Shape Optimization
In order to solve a wide range of structural optimization problems numerical methods are applied. The design function s, which describes e.g. the geometry of the structure, and the state variables, e.g. the displacements u, are discretized. The mechanical problem is most often solved by finite element methods, the in general nonlinear constraint parameter optimization problem by mathematical pr...
متن کاملPractical Bayesian Optimization of Machine Learning Algorithms
The use of machine learning algorithms frequently involves careful tuning of learning parameters and model hyperparameters. Unfortunately, this tuning is often a “black art” requiring expert experience, rules of thumb, or sometimes bruteforce search. There is therefore great appeal for automatic approaches that can optimize the performance of any given learning algorithm to the problem at hand....
